[Mesa-users] Building a working opengl32.dll?

[Charles Huber]

For the Mesa 9.0 tarball is there a combination of OS, compiler, and
SCons invocation that will produce a working opengl32.dll for Windows?

I've been trying to run the attached test program (In Debug mode) in
VS2010 Express using FreeGLUT 2.8.0.  It should display a spinning red
square with a blue top-right corner.


Building on Linux (Ubuntu 12.04, MinGW cross-compiler):
scons -j 4 \
build=release \
platform=windows \
toolchain=crossmingw \
mesagdi

Stops on line 36 (glRotatef( angle, 0, 0, 1 );) with:
"First-chance exception at 0x007cc640 in glHarness.exe: 0xC0000005:
Access violation."


Building on Windows 7 (MinGW + MSYS, using the VS2010 Express compiler):
scons.py -j 8 \
build=release \
platform=windows \
mesagdi
